BOOK-MATCH MACHINE.

Original application filed Apri1- 30, 1925, Serial No. 27,110. Dividedand this application filed January 6, 1923. Serial No. 244,806.

This invention relates to machines for making book matches and this aplication, which is a division of Ser. No. 2 ,110, filed April 30, 1925,is directed to mechanism for 5 accurately positioning match book coverstock to be operated upon by a cutter to form cover blanks.

Mechanism of this character has been found highly desirable for numerousreasons among which may be mentioned the production of books ofuniformwidth, and the uniform positioning of the printing on the matchbook covers.

Features of the invention, other than those specified, will be apparentfrom the hereinafter detailed description and claims, when read inconjunction with the accompanying drawings.

he accompanying drawin illustrate one practical embodiment of t einvention,

but the construction therein shown is to be understood as illustrative,only, and not as defining the limits of the invention.

Figure 2 is a perspective view showing portions of the machine of Figure1 removed from such machine and illustrated in diagrammatic relation tomore clearly show the structure of these parts; and,

Figure 3 is a diagrammatic view illustrating different positions ofwhich the mechanism for accurately positioning the book matchstockpartake during the operation of the machine. I

Referring to the drawings, it will be observed that the paper stri 14passes into the machine between the ared ends of the guides 39 and 40,and between the rollers 41 and 42 over the pan 128, the roller 41 beingmounted in th-bearin s 43 and 44, and the roller 42, upon the s aft 45carrying the ratchet wheel 46 in the path of the pawl 47 secured uponthe pin 48 of the lever 49 which is adapted to oscillate upon the shaft45. 50 is'the drive shaft of the machine and carriesthe cain 51, oneside of which engages the roller 52 at the lower end of the rod 53pivotally mounted at 54- and secured at the upper end by the spring 55anchored to the frame 56 of the machine.

At the upper end of the lever 53 is pivotally secured the rod 57connected by turn-buckle 58 to the rod 59 pivotally connected to thelower end of the lever 49, so that as the latter is oscillated u on theshaft 45 by action of the cam 51, t e pawl 47 engaging the ratchet wheel46. periodically rotates the same one tooth at a time, thereby causingthe feed roller 42 upon which the paper strip 14 rests to feed the same,the roller 41 pressing thereon by spring tension as usual in such feeds.

Referring to the feed of the roller 41 upon the shaft 41, it will beobserved that a shaft or rod 88 is provided with an offset 89immediately beneath the shaft 41' so that as the shaft or rod 88oscillates, the roller 41 is intermittently lifted from the sheet orstrip 14, thereby intermittently discontinuing the feed thereof, theshaft or rod 88 being provided with brackets 89' and also having an arm90 pivotally connected to the link 91, the lower end of which isprovided with a roller 92 ada ted to ride upon the cam 93 upon the shaft5.

The purpose of the rollers 41 and 42 is to feed the strip 14longitudinally of the machine to a knife or'cutter 96. This feed isintermittent and the knife operates while the strip 14 is at rest. Thus,the rollers 41 and 42 feed a predetermined length of the strip 14, arethen disengaged therefro'm and while they are disengaged and the stripis at rest, the cutter 96 operates to cut off a portion of the end ofthe strip. The cutter is mounted for movement with the slide'97 guidedin a suitable block 87 and is actuated by a lever 98 pivoted at 99 andhaving a link connection 100 on which is mounted a follower 101cooperating with the .cam 102 fixed onthe main shaft 50. The details ofthe cutter and its associated mechanism are fully described in' thecopending application of which this case is a division and furtherdetails thereof need not be given here. In practice, any suitable cuttermay be employed. It is the primary purpose of this invention, however,to render accurate the feed of the strip 14 so that at successiveoperations of the cutter 96, uniform lengths o the strip may be severedtherefrom and the cuts properly spaced with reference to printing on thereverse side of the cover blanks. The mechanism whereby this may beaccomplished will now be described.

60 indicates a suitablebracket secured upon the side frame 56 of themachineby a screwor bolt such as 61 and having an elongated slot 62 thruwhich the screw or bolt 63 passes, thus allowing for the adjustment ofthe bracket 60 upon its pivotal support 61. The bracket 60 providesbearing for the shaft 64, said shaft being rigid with an arm 65 which inturn is pivotally connected to the link 66 ivotally connected at theopposite end to the lever 67 pivotally mounted at 68 in the side of themachine 56 and retained by the spring 69 anchore'd at 70, the oppositeend of the lever 67 being pivot-ally connected at 71 to the link 72, thelower end of which is provided with a pin 73 which rides upon the cam 74under the countershaft 75 having gear 76 driven by pinion 77 upon thedrive shaft 50. From this it will be seen that with each rotation of thedrive shaft 50, the shaft 64 is oscillated, and upon the other end ofthe shaft 64 is-mounted a housing 78 which has pivotally mounted in theu per part thereof the bracket 79 carrying 1: e resilient finger 80, andin the lower part of said housing is pivotally mounted the racket 81having finger or entering point 82. The bracket 81, it will be observed,extends beneath the bracket 79, and 83 is a tension spring between saidbrackets tending to keep the fingers 80 and 82 depressed. Accordingly,as the shaft 64 oscillates in a clockwise direction as viewed in Figure1, the fingers 80 and 82' feel for and enter, in successlon, cooperatingperforations 15 in the paper strip 14. As this 0 eration occurs whilethe roll 41 and the knife 96 and foot 109 are elevated, the paper striis free to shift longitudinally. It there ore follows that when theshaft 64 has been oscillated to its full extent in the direction stated,the fingers 80 and 81 will have served to shift the strip longitudinallyinto proper adjusted relation with respect to the knife 96, so that whenthe knife subsequently descends, the

cut is correctly positioned with respect to the length of the strip, thefingers holding the strip until the cut is completed. The bracket itwill be observed continues upwardly providing a bearing 84 which isthreaded to receive the screw 85, the end of which engages threads inthe offset 86 of the block 87 so that by turning the screw 85 the angleof the bracket60 upon the pivotal support 61 maybe varied and the feedof the ers 80 and 82 may be slightly retarded or advanced as may befound necessary.

The operation of the parts 80 and 81, which may be termed feeler fingersbecause of their peculiar function is dia 'ra'mmatically shown in Figure3. When the shaft 64 is oscillated into its normal 'osition, the housing78 extends substanti y vertically as shown in Figure 3. At this time,the free ends of the fingers 80 and 81 will be drawn toward one anotherso that they are now at the minimum distance apart as illustrated infull lines in Figure 3. As the finger 80 moves into this position, itengages. with. a projection 80*, which lifts the finger slightly so thatwhen in the full line position of Figure 3, the free end of the finger80 will be free from the paper strip 14. When, however, the shaft isoscillated in a clock- Wise direction, the parts move from the full lineposition of Figure 3 into the dotted line position of this figure.During this opera tion, the fin ers 80 and 81 both engage with the faceof t e paper strip as they are moved apart and if, during its movement,the strip is not in exactly the correct longitudinal adjustment withreference to the knife 96, one or the other of the fingers will engagewith one of the perforations 15 and cause the paper to be shiftedlongitudinally in one direction or therother in order to obtain thedesired adjustment.

As long as the fingers 80 and 81 are in the position shown in full linesof Figure 3, the projection 80 will slightly elevate the finger 80 sothat the strip 14 can travel without the finger engaging theperforations therein. During this same period, the free end of finger 81will be free to slide over the strip because the beveled lower end ofthe finger will cause it to be elevated out of the perforations when thestrip moves. In other words, the fingers 81 can only act positively toshift the strip when said finger is moved to the left and the finger 80can onlgvglrlct positively when moved to the right. on retracted, bothfingers slide idly over the strip.

When the parts move from the full to the dotted line positions of Figure3, if the strip has slightly lagged during the previous'feed of therollers 41 and 42, the finger 81 will engage a perforation and shift thestrip forward into correct position. But, if the strip has been overfedby said rollers,

then the finger 80 will engage with a perforation to move back the striinto proper position. At the completion 0 the working operation ofthe'fingers, bothare in corresfiplonding perforations of the strip andas the f gers v are retracted they are withdrawn from both perforationsand returned to the full line position of Fig. 3', whereupon the nextfeeding operation of the rollers 41 and 42 takes place.

It will of course nection that the perforations 15 in the paper areaccurately spaced apart, so that through the manipulation of the stripas described,

the cutting of the strip b successive operations of the knife 96 wi beuniform. In other words, uniform lengths of the strip will be cut atsuccessive operations.
